This invention relates to a lining and beveling machine, primarilydesigned for the use of photoengravers, and has for an object to providesuch a machine in which the carriage and table are offset laterally fromthe pedestal, and the outer longitudinal edges of the carriage and tableare rigidly supported throughout the entire length of travel in bothdirections, thereby permitting the M increase in speed of movement andminimizing the friction of the parts.

Another object consists in providing such a machine in which the supportfor the outer longitudinal edges of the carriage and table in theirtraveling movement includes a straight line parallel motion meansconnected to the pedestal and carriage and movable therewith, wherebygreater accessibility of the work on the table is obtained.

Another object consists in providing certain improvements in the form,construction and arrangement of the several parts, whereby the abovenamed and other objects may effectively be attained.

A practical embodiment of my invention is represented in theaccompanying drawings, in which Fig. 1 represents a side elevation ofthe machine;

Fig. 2 represents a front elevation of the same;

Fig. 3 represents a detail vertical section, taken in the plane of theline III--III of Fig. 1, looking in the direction of the arrows;

Figs. 4 to 7 inclusive represent detail vertical sections, on a largerscale, taken in the plane of the lines IV--IV, V-V, VI-VI, and VII-VIIof Fig. 1 respectively, looking in the direction of the arrows; and

Figs. 8 to 10 inclusive represent diagrammatic views of the straightline parallel motion means with the carriage shown in diiferentpositions throughout its length of travel.

The machine includes a base I, a pedestal 2 uprising therefrom, acarriage 3, one longitudinal side of which is supported by a V-shapedrail 4 secured to the side of the pedestal by bolts 5, and a table iifor receiving the plate to be operated upon, which table is secured tothe carriage 3 in any well known or approved manner, so that thecarriage and table are reciprocated during the operation of the machine.The other or outer longitudinal side of the carriage 3 is supported by astraight line parallel means which comprises a series of links connectedtogether and arranged to move about two centers of motion. The links l,8, 9 and in are substantially of equal length and are pivoted togetherby bolts H, l2, I3 and M, in the form of a rhombus. The pivot bolt I tof the links '1 and I0 is also connected with the upper end of a linkl5, while the upper end of a link I6 is connected with the links 8 and 9by the pivot bolt l2. The links l5, it are substantially equal inlength,and the lower ends of the links are connected by a pivot bolt l! tooscillate in a bracket l8 carried by a plate l9, which is fixed to theside of the pedestal 2 by bolts 20. Thepivot bolt l3 of the links 9 andit connects the upper end of a link iii, the lower end of which ispivoted on a stud bolt 22 fixed on the plate IS. The links I, 8,together with their pivot bolt Ii, are secured in a bracket 23 fixed bythe bolts 24, 25 to depend centrally of the longitudinal edge of thecarriage 3.

In order to minimize the friction of the pivoted joints of the links, Iprovide anti-friction bearings of which the upper end of the link I hasa ball bearing 26, while the upper end of the link 8 is bifurcated at2'! (Fig. 4) and frictionally secured to the pivot bolt H, which isjournaled in ball bearings 28, 29 carried by the bracket 23. The lowerend of the link I is bifurcated at 30 (Fig. 5) and frictionally securedto the pivot bolt M which is journaled in ball bearings 3|, 32 carriedby the upper end of the oscillating link IS. The upper end of the linkII] which is also pivot-ed on the bolt [4 is provided with ball bearings33.

Anti-friction bearings associated with the pivot bolt 52 and itscoacting lower and upper ends of the links 8 and 9 respectively, and theupper end of the oscillating link !6, are similar to that shown anddescribed with respect to the pivot bolt I4, links 1, l0 and I5, so thatfurther description is therefore deemed unnecessary.- The lower end ofthe oscillating link E5 is provided with a ball bearing 34 which coactswith the pivot bolt ll, while the lower end of the oscillating link itis bifurcated at 35 and frictionally secured to the pivot bolt IT. Thepivot bolt I'l is journaled in ball bearings 36, 31 carried by thebracket l3, as shown in Fig. 7. The upper end of the oscillating link2|, which is connected with the lower end of the links 9, I [i by thepivot bolt I3, is also provided with ball bearings (not shown) similarto the ball bearing shown described with respect to the links 1, l0 andpivot M, so that further description is deemed unnecessary. The lowerend of the oscillating link 2! is provided with a ball bearing 38 whichcoacts with the pivot stud bolt 22 carried by the plate I9, as shown inFig. 6.

As a result of the construction above described, it will be seen thatthe carriage is held in position and accurately guided by the rail 4,while the link means adequately support the other or outer longitudinalside of the carriage and permit its reciprocating movement with aminimum resistance.

The means for reciprocating the carriage 3 includes a hand wheel 39which is fixed on a rod til that is journaled in a swinging bearing Mwhich is carried by a bracket 42 fixed to the side of the carriage, asshown in Figs. 1 and 2. A screw bolt 33 serves as a pivot to permit thebearing M to swing in a vertical plane on the bracket 42. The rod 4%)pierces the adjacent side of the carriage 3, as indicated at M, and theinner end is furnished with a helical gear 65 that normally meshes witha rack 48 that is clamped by bolts 5 to the V-shaped rail 4 and hence isfixedly secured to the pedestal 2.

From the foregoing, it will be seen that turning the hand wheel 39 willslide the carriage on its rail and the link motion, by virtue of theengagement of the helical gear 25 with the rack 58 and with the handwheel 38 and the con nected parts, will travel with the carriage 3 inits movement. This provides a very smooth and positive action because ofthe character of the intermeshing parts and the traveling movement a swith the table of the actuating gear 45 and connected elements. Thehelical gear, or the like, will always have at least two teeth in meshwith the rack because of the angularity of the teeth, which effects aneven and precise movement;

1 and such an arrangement also allows the shaft which operates thehelical gear to be placed at an acute angle to the rack, whereby itsoperating hand wheel may be convenient to the operator of the machinewithout being in his way. Furthermore, a gear of the helical type tendsto prevent chips from clogging the rack, because the engaging movementof the parts is such as to urge the chips out of the rack instead of tohold them therein and crush them.

When the carriage with the table thereon is reciprocated in theoperation of the machine from one position to another, the link motionwill assume difierent positions such as that shown diagrammatically inFigs. 8 to 10 inclusive, and the links will move in the direction oftravel, as indicated by the several arrows. The actuation of thecarriage 3 transmits its motion through. the bracket 23 and its pivotbolt Ii to the links I and 8 which move the links 9 and is through thepivot bolts l2, l3 and 14. This movement of the links '5 to it inclusiveand their pivot bolts Ii to M inclusive is transferred to the link 25which is oscillated on its stud bolt 32 fast on the plate 19 which isfixed to the side of the pedestal 2. Simultaneously the links it and itwill be oscillated on the pivot bolt ll journaled in the bracket it onthe plate lit by their connections Hi and E2 of the links 1' to illinclusive. Thus it will be seen that, by

r the co-operation of the several links with their pulley 5!! from asuitable source of power (not shown).

The clamp 5| for securing the work to the table is herein briefly statedas being capable of moving vertically toward and away from the work, theconstruction and operation of which is well understood by those skilledin the art.

The machine also includes a head for a variety of lining tools or thelike, which is indicated generally by 52 (see Fig. '1). The constructionand operation of this head for the lining tools is set forth in UnitedStates Patent No. 1,226,912, dated May 22, 1917, so that the same willnot be detailed herein.

The operation of the various parts of the machine has been described inconnection with setting forth their construction, so that it is notregarded as necessary here to re-state the operation of the machine as awhole.

It may, however, be noted that the construction and arrangement welladapts the machine for attaining the objects hereinabove outlined andothers inherent in its construction, and that its design contemplatesefficiency, accuracy and speed in operation, together with generaladaptability for meeting varying needs of this particular class of work.

It will be understood that various changes may be resorted to in theform, construction and arrangement cf the several parts withoutdeparting from the spirit and scope of my invention; and hence I do notintend to be limited to the details herein shown and described, exceptas they may be included in the claims.
